error while loading shared libraries tv sample

Hi,

Has anyone got an idea how to resolve the following error?:
./upnp_tv_ctrlpt: error while loading shared libraries:
libthreadutil.so: cannot open shared object file: No such file or
directory
the upnp_tv_ctrlpt file and the libthreadutil.so file are in the same
dir (libupnp-1.2.1/upnp/bin). (file permissions are ok)

Thanks!!
Henk
